A sweet rainforest fruit eaten traditionally when fully ripe. Indigenous Australians softened firm plums by fire or sun to reduce bitterness, and sometimes dried them into transportable fruit cakes. The dense, dark timber was used for small tools and digging sticks. Black plum is a keystone wildlife food, feeding birds, possums and fruit bats, and helping regenerate healthy rainforest edges.

Indigenous Uses

1. Bush Tucker – eaten fully ripe

• The plum was eaten when it turned a deep purple or black and softened, developing a sweet, wine-like flavour.

• A partly astringent plant, it was often left to wrinkle or ferment slightly on the tree or on bark trays to remove bitterness.

• Some groups mashed the soft fruit and dried it into leathery cakes to carry between camps.

2. Cooking to reduce astringency

• The unripe fruit is astringent due to tannins.

• Indigenous groups sometimes:

  • Roasted firm fruits in warm coals

  • Left them in woven baskets near the fire to soften

• The heat reduces tannins and brings out a deeper sweetness.

3. Mild medicinal uses

Though not a major medicine plant, it had a few uses:

• The fruit flesh was sometimes used as a gentle remedy for:

  • Minor digestive upsets

  • Mild dehydration (due to its hydrating, soothing pulp)

• The leaves, when crushed, were used as a skin-wash for:

  • Small cuts

  • General cleansing

4. Timber and practical uses

• The wood is exceptionally dense, heavy and fine-grained.

• Indigenous groups used it for:

  • Digging sticks

  • Clubs or short wooden tools

  • Burnishing / smoothing tools

• The wood’s weight and durability made it a reliable choice for hand tools.

Stories, Culture & Interesting Lore

1. “Plum of the rainforest edges”

• Elders sometimes say that the black plum tells you when you’re entering healthy rainforest country.

• It grows at the transitional edges — a meeting place between open forest and deep rainforest — and was seen as a boundary marker species.

2. Fruits that “call the birds”

• The ripening fruit attracts:

  • Wompoo fruit doves

  • Figbirds

  • Currawongs

  • Possums

• In some stories, the fruit is described as a signal for bird migration and a reminder of seasonal movement.

3. A quiet “sharing tree”

• Because the fruit falls when ripe, it was known as a plant that “feeds whoever arrives,” human or animal.

• Children often collected fallen fruit from beneath the tree.

• Some groups called similar Diospyros species “bush lollies from the ground.”

4. Related to the ebony tree

• Diospyros is the same genus as true ebony.

• Some Dreaming stories explain that the blackness of the fruit and the dark beautiful timber come from a spirit ancestor who hid himself inside the tree, giving it “the darkness of night.”

Modern Uses

1. Culinary uses

The ripe fruit can be:

• Eaten fresh

• Cooked into jams, relishes, or chutneys

• Fermented into a tangy beverage or cordial

• Dried into fruit leather

• Added into muffins, cakes or desserts

The flavour is sweet with earthy undertones — like plum with a hint of red wine.

2. Ornamental & landscaping

Diospyros australis is popular in regenerative landscaping because:

• It is hardy and visually attractive

• Its dense canopy provides habitat

• It’s fire-sensitive but regenerates well

• It attracts wildlife

Great for:

• Bush tucker gardens

• Rainforest regeneration strips

• Rewilding school projects

3. Timber craft

• Woodturners value it for beautifully smooth tools and small decorative items.

• Its density makes it ideal for:

  • Carving

  • Handles

  • Mallets

Ecological Importance

Wildlife that feed on the fruit

• Wompoo fruit dove

• Green catbird

• Lewin’s honeyeater

• Possums

• Flying foxes

They help spread the seed across the forest.

Rainforest regeneration

• Black plum is considered a pioneer-to-mid-succession tree.

• Establishes early after disturbance and supports later rainforest species by:

  • Providing shade

  • Dropping leaf litter

  • Holding moisture
